This invention relates to weather caps for electrical lead-in conduits.

The general object of the invention is to provide a weather cap simplein construction, capable of easy assembly, yet affording full protectionJfrom the ingress of moisture or dirt.

Another object is to provide securing means for the cover piece which ispermanently carried by one of the major elements of the assembly, doesaway with the necessity for handling small, loose parts, and avoids thealignment of the screws in threaded apertures at the time of assembling.

Another object is to provide a Weather cap composed ot only two simplecastings which are inexpensive to manufacture and which, when assembledwith insulator and screws in the manner hereinafter set forth, consistsoic only the two separable parts.

With these and other objects in view, the invention consists in thevarious novel features of construction and combination, all of whichwill be fully described hereinafter and pointed out in the appendedclaims.

in the accompanying drawings I have shown an embodiment of my invention,wherein Fig. 1 is an elevation oi' the weather cap assembled on thelead-in conduit; Fig. 2 is a sectional elevation of the weather cap;Fig. is a bottom plan view of the weather cap showing the insulatorblock with conductor openings; Fig. 4 is a sectional view on line 4 4 ofFig. 2; Fig. 5 is a sectional view on line 5--5 of Fig. 2 and Fig. 6 isa fragmentary section on line 6-6 of Fig. 5.

Describing by reference characters the various parts of the embodimentillustrated in the accompanying drawings, 1 is the usual y uprightconduit extending from the elbow 2 which in turn connects with a conduitthat eX- tends through the wall or other building part the body memberand extends over the .in-

sulator/block 6 which is in turn securely fastened to the body 4. j

The body member 4 is composed of the Vtubular portion 7, `shown asinteriorly threaded for the reception of the conduit 1, and having atits upper end. a base 9 that. is surrounded by an upwardly extendingange 10, and from the front of whichv pro]ect iners V11. angel() atopposite sides of thebody memberare lugs 12 which have threadedapertures to receive screws 14. The screws 1.4 after boing passedthrough the lugs are upset as at 13V toprevent their removal or lossinshipment or handling, but still permitting longitudinal movementsuicient to eiect the engagement or disengagement with the cover 5aswill be hereinafter described.y

Extending inwardly at thetop ofthe tubular portion- 7V is a circularflange 15 which forms a shoulder 16 against whichl the conduit 1 may,strike when thesmember 4 is secured thereto. The inner periphery ofthis flange'i maybe rounded as shown to'present a smooth edge-which willnot cut or scrapethe conductor insulation as it is drawn'` therethrough.At the junction ofthe lingers 11 with the base portion 9 is areinforcing flange 9* shown in Fig. Q, which also forms an abutment'again-st whichthe insulator member 6 isheld.

The insulator member 6 iscomposedof any suitable insulating material andis'secured to the fingers 11 by astening'meansl?, such as rivets. Theinsulator member 6 isrprovid'ed with apertures 18 to receive theconductors 3. Tovaccoinmodate aathird' wire, in case a threephasekcircuit is used, the member 6 is provided with; av knocleout opening.'19 that is vnormally closed by a blank 20. y

The cover member 5' is constructed to'ft about the flange' 10 with afront portionv 21 extending downover the fingers 11 and over theinsulator member V(iso-as to substantially coverr the same. Tolimitl thedownward movement of the cover over the body4, the cover=member isformed with a lug 22 which engages the upper edge of the iange 10.

At opposite sides of the cover 5, and matchi Extending upwardly from theyaIt ing up with the screws 14 when the cover and body are assembled,are slots 23 to engage down over said screws at the lower edge of thecover and on opposite sides thereof are outwardly extending flanges 24which are cut by the slots 23 providing shoulders 25 to be engaged bythe heads of the screws 14, when the same are screwed in thereby toprevent removal of the cover.

The weather cap as received by the electrician for installation consistsas will be observed of only two separable parts; the body member 4having the insulator 6 already secured thereto and screws irremovablyscrewed into the lugs 12, and the cover member 5. i

No loose parts are present to slip from the hands of the electricianwhile assembling the cap on the job, nor is it necessary to align thescrews 14 with threaded apertures in securing the cover member 5 inplace.

In assembling the cap, the body 4 is secured to the conduit l, theconductors 3 threaded into place and connections made with theconductors from the conduit l. The screws 14 are backed out as tar asnecessary to allow the flanges 24 to pass and the cover member placed inposition with the screws 14 entering the slots 23. rIhe screws aretightened whereby the screw heads engage the shoulders 25 and securelylock the cover in place.

Having thus described my invention, what I claim is:

1. A weather cap for electrical conduits comprising a body memberprovided with means for attachment to a conduit, a cover for said bodymember adapted to lit over the upper edges thereof, locking means forsaid cover comprising laterally extending headed bolt members onopposite sides of said body adapted for longitudinal movement, saidcover being provided with laterally extending langes on opposite sidesthereof and slots extending from the edges of said Cover through saidflanges providing shoulders adapted to be engaged by the heads of saidbolt members when the cover is in place on the body to securely lock thesame thereto.

2. A weather cap for electrical conduits comprising a body memberthrough which conductors are adapted to pass, a cover member having itslower edges extending over the upper edges of said body member, flangeson said cover, said cover being provided with slots extending from theedges thereof through said flanges, headed bolt means on said bodyadapted to be received in the slots when the cover is in place, theheads of said bolt means adapted to engage over the ianges to lock thecover in place.

In testimony whereof, I hereunto attix my signature.

JOI-IN C. BOYTON.
